LI-1500
Light Sensor Logger
The LI-1500 Light Sensor Logger is a portable instrument used to measure light intensity and duration. It is commonly used in plant research and agriculture to measure photosynthetically active radiation (PAR) and other forms of light that affect plant growth and development.
The LI-1500 consists of a light sensor connected to a data logger, which records measurements of light intensity and duration over time. The sensor can be used to measure light in a variety of settings, including in the field, in greenhouses, and in growth chambers.
The LI-1500 can be programmed to take measurements at specific intervals, and the data can be downloaded and analyzed using LI-COR's software. This allows researchers to track changes in light intensity over time, and to correlate these changes with plant growth and other variables.

Fast measurements (up to 500Hz)
Intuitive, menu-driven interface
Intuitive, menu-driven interface
The menu-driven interface is easy to use. Attach your LI-COR light sensor(s) to the three BNC connectors. Log manually or use menus to set up one-time, daily, or continual measurement routines. Sampling rates and logging intervals are user-selectable.Fast measurements (up to 500Hz)
Use the LI-1500 with one sensor to sample and log measurements up to 500 Hz — fast enough to measure the flicker rate of fluorescent, iridescent, incandescent, and LED light bulbs. Graph these large data sets on your computer using LI-COR’s FV7x00 software, available for free download. Also view real-time light measurements, GPS data, and other variables on the eight-line display screen.LI-1500 Specifications
